• Mounting the shaft or fitting the shrink disk on the shaft.
If the gear unit is fitted in a vertical position with the output shaft down, the fitted shrink
disk must be protected from dropping.
The outer surface of the hollow shaft may be greased in the area of the shrink disk seat.
Never clamp the shrink disk until the machine shaft has been mounted.
• Remove screw plugs from the "Clamp" and "Release" connections.
Collect any hydraulic fluid that may run out!
Connect the pressure line to the connection marked "Clamp".
Clamping of the shrink disk.
The correct clamping condition has been reached as soon as the faces of the outer and
inner rings are flush.
The maximum permissible clamping pressure is 450 bar!
This allows the clamping condition to be checked visually.
If alignment cannot be achieved by clamping, consult Siemens.
• Turn lock nut finger­tight against the outer ring.
• Relieve oil pressure. This will cause the outer ring to be forced firmly against the lock nut by the
previously stored energy.
• Screw screw plugs back into the "Clamp" and "Release" connections. Leave the hydraulic fluid in the
shrink disk.
For safety reasons, a protective cover should be mounted above the shrink disk.
